Representing Heterogeneous Data (2023)
← → August 04, 2023 As I mentioned in the last post, I’m working on taking my little videogame scripting language and turning it into a statically typed one. As much as possible, I’m trying to make the language simple and familiar.
There is one other approach to heterogeneous data that I found that I didn’t put in the list up there because, as far as I can tell, it’s basically a dead end in the evolutionary history of programming languages. A variant record in Pascal (as I understand it from the half dozen ancient slideshows I’ve been able to find about it) essentially models that pattern directly. I’d be more inclined to do sum types and destructuring, even though it feels a little weird in an imperative language, then do this kind of complex control flow analysis.
